Obama is a centrist Republican says Glenn Greenwald in today's Guardian. That's about right. As the Republican candidates try to be more to the right than Obama already is the policy discussion in the United States moved further to the rightwing fringe.
The Overton window, the frame of political acceptable ideas, is now more militaristic, more anti-social and less liberal than it has been for decades. As Obama has unfortunately no primary competition the only bit of hope for change in general U.S. policies comes with the one anti-war candidate in the whole field.
Ron Paul's libertarian ideas on social issues and financial matters are, in my view, quite nutty. Even more so than the positions of some of his fellow candidates. But his position on war and foreign affairs seem very reasonable to me. If he can get a higher profile by winning primaries his ideas will become more public and acceptable. The Overton window will widen and that again may induce more people to work against the established militaristic trend.
Justin Raimondo predicts that Ron Paul victories in some primaries will not change the predictable end-result in this election cycle. Obama will win:
In the end, a coalition of neocons and Romneyites will issue an encyclical, excommunicating Paul and his supporters from the Republican party – and opening the way for a third party bid that will threaten to put the GOP nominee in third in November.
That may well be the case. I would consider it a great success though because that process will turn discussions about war into something different than today's wholesale acclamations on both sides of the aisle to follow Netanyahu's calls to bomb Iran.
That should be reason enough for any progressive to vote for Ron Paul wherever possible.
